The Department I work for will not allow any modifications whatsoever. Over the years they have upgraded grips and sights and have changed what is the approved ammo but we can not do anything to them. NY is an anti gun state and if I deviate from what they approve my instructors have made it clear I am on my own. Coming from this type of constraint I will not carry a modified handgun. If I modify it will be for range use or local competition.
